The Karen /kəˈrɛn/, or Karenic, languages are tonal languages spoken by some seven million Karen people. They are of unclear affiliation within the Sino-Tibetan languages. The Karen languages are written using the Burmese script. The three main branches are Sgaw, Pwo, and Pa'o. Karenni (also known Kayah or Red Karen) and Kayan (also known as Padaung) are related to the Sgaw branch.
